 * AuthPluginV2 - Extracts authentication credentials from request headers.
 *
 * This plugin is part of the v2 authentication system (Auth0 integration).
 * It ONLY handles credential extraction. Verification and context creation
 * are delegated to the AuthContextProvider (Phase 4).
 *
 * Responsibilities:
 * 1. Extract `Authorization: Bearer <token>` (JWT)
 * 2. Extract `X-API-Key: <key>` (API Key)
 * 3. Add `rawAuth` object to Yoga context
 *
 * NOTE: This plugin intentionally runs alongside the legacy auth plugin
 * during the migration phase. It does NOT throw errors or block requests.
